Both men suffered injuries in the lead-up to the contest, which was
expected to take place Dec. 28 at MGM Grand Garden Arena in Las
Vegas.

UFC 168 airs live on pay-per-view and is headlined by a
middleweight title rematch between reigning champion Chris
Weidman and former 185-pound ace Anderson
Silva. The event will also showcase a women’s bantamweight
title rematch pitting Ronda
Rousey against Miesha
Tate.

Del Rosario, 30, has not competed since December 2012, when he was
knocked out by Pat Barry at
“The Ultimate Fighter 16” finale. The setback marked the
Strikeforce veteran’s second consecutive defeat, as he was also
stopped by Stipe
Miocic at UFC 146. Prior to those losses, del Rosario had been
perfect as a pro, winning his first 11 bouts by either knockout or
submission.

Better known as “Guto Inocente,” Filho has not fought since May of
last year, when he outpointed Virgil
Zwicker in a one-sided, unanimous decision under the
Strikeforce banner. Prior to that triumph, the 27-year-old won
three straight bouts in his home country of Brazil, including a
pair of stoppages within the Shooto Brazil organization.
